Ah, gotcha. It seemed less likely, but I wasn't certain.

So far I haven't crashed once (*knock knock*) since the BIOS update and the consequent speed drop.

Does anyone have a good link for where I can learn about overclocking my system? Like I said, I have a really good HS/F on my 920 CPU, and I don't want to crank it up to 4GHz or anything, but I've heard that 3.2 is typically safe with the stock HS/F, so I figured it would be very safe with my giant HS/F. Seriously, this thing is huge! As you can see below. Those are two 120mm fans on the sides of the heatsink. Here's the one I have.
